AB  - In wide-area wireless sensor networks, network lifetime is short due to energy consumption and transmission distance. To improve this problem, we divide the sensor field into layers and reduce transmission distance through multi-hop method. However, there is a problem in that the transmission rate drops because there is no cluster head in the layer or the transmission distance increases due to the layer and energy is wasted. There are DL-LEACH (Dual-hop Layered-LEACH) and EDL-LEACH (Enhanced Dual-hop Layered LEACH) as protocols to improve this. DL-LEACH uses either single-hop transmission or multi-hop transmission depending on the situation. As a result, the transmission distance is optimized, thereby reducing energy consumption. In case of EDL-LEACH, it is proposed to improve the data rate in DL-LEACH. It is the same as DL-LEACH but the cluster head is mandatory for all layers to improve the transmission rate. Although, there is no cluster head for each layer, the transmission rate is improved, but the network life is shortened. In this study, we try to improve the network lifetime while maintaining the EDL-LEACH transmission rate. The shortened network lifetime is due to cluster head overload near the base station. To improve this the cluster head distribution method is improved and the network lifetime is improved.
